Description
Technical Field
The utility model relates to a joint bar location frock especially relates to an assembled joint bar location mount.
Background
The grouting sleeve connection is the main connection mode of the stressed steel bars of the prefabricated concrete structure, and the accurate correspondence between the sleeve and the position of the inserted steel bars is a key factor for ensuring the safety quality of the prefabricated concrete structure. In the process of mounting the prefabricated part, the shear walls on the standard layer and the top layer can be accurately mounted through the sleeve joint bars reserved on the shear wall on the lower layer, but the technical requirement is high in the construction process of reserving the joint bars on the conversion layers of the cast-in-place layer and the prefabricated layer, and the construction difficulty is high.
The length of the reserved dowel of the prefabricated part in the prefabricated concrete structure is only 8D +20, and the inner wall edge of the steel bar sleeve is only a few millimeters wider than the inner wall edge of the steel bar sleeve. The deviation of reserved steel bars directly causes the vertical member to be hoisted when exceeding the inner wall of the sleeve, and the hoisting is in place, if the problem occurs, the construction site is completely stopped, the next step of working procedure can not be carried out, the construction progress is seriously influenced, and the huge waste of member cost, labor cost and mechanical cost can be caused. When the positioning deviation of the reserved dowel bar exceeds the allowable deviation by 3mm in the sleeve, even if the prefabricated part can be hoisted successfully, the flatness and the verticality of the outer wall are affected, the grouting quality of the steel bar connecting sleeve cannot meet the requirements, and the construction quality of the project cannot be guaranteed, so that the importance of accurate positioning of the reserved dowel bar of the prefabricated concrete structure can be seen.
The existing dowel positioning tool is mainly used for manufacturing a positioning support plate by wood or metal, and then punching is carried out on the support plate according to the position of a dowel so as to insert a steel bar into a hole to achieve the purpose of positioning. But the tool has the obvious defects that: firstly, the bar inserting tool is poor in universality and low in repeated utilization rate, holes need to be punched again every time the position of a bar inserting tool is changed or the size of a steel bar is changed, and when holes punched on a support plate are too many, no new holes are punched in the remaining space, and the support plate needs to be machined again; secondly, the strength of the support plate is gradually reduced along with more holes punched on the support plate, so that the construction quality is easily reduced; thirdly, because the spiral rib is evenly arranged on the periphery of the steel bar, the steel bar is inserted into the hole of the support plate, the inner wall of the hole is firmly attached to the outer diameter of the rib part of the steel bar, so that the steel bar can be fixed, but when the steel bar is inserted into the hole, the inner wall of the hole is positioned at the inter-rib part of the steel bar, so that the steel bar cannot be completely attached, a certain gap is formed, the steel bar is easily shaken or deviated, and inaccurate and unstable positioning is caused.
